STUN Client and Server

•    C++

---

This project implements a simple STUN server and client on Windows, Linux, and Solaris. The STUN protocol (Simple Traversal of UDP through NATs) is described in the IETF RFC 3489, available at http://www.ietf.org/rfc/rfc3489.txt

pystun - A Python STUN client for getting NAT type and external IP

•    Python

---

A Python STUN client for getting NAT type and external IP. PyStun follows RFC 3489, A server following STUN-bis hasn't been found on internet so RFC3489 is the only implementation.

coturn - Free open source implementation of TURN and STUN Server

•    C

---

The TURN Server is a VoIP media traffic NAT traversal server and gateway. It can be used as a general-purpose network traffic TURN server and gateway, too. On-line management interface (over telnet or over HTTPS) for the TURN server is available.

signalmaster - simple socket.io server for webrtc signaling

•    Javascript

---

A simple signaling server for clients to connect and do signaling for WebRTC. It also supports vending STUN/TURN servers with the shared secret mechanism as described in this draft. This mechanism is implemented e.g. by rfc-5766-turn-server or by a patched version of restund.

My SIP Switch

PyPunchP2P - Python实现NAT穿透+STUN+TURN+P2P聊天 | Python P2P chat

•    Python

---

Python p2p chat client/server with built-in NAT traversal (UDP hole punching). I've written an article about the detailed implementation (in Chinese). The number 100 is used to match clients, you can choose any number you like but only clients with the same number will be linked by server. If two clients get linked, two people can chat by typing in terminal, and once you hit <ENTER> your partner will see your message in his terminal. Encoding is a known issue since I didn't pay much effort on making this tool perfect, but as long as you type English it will be fine.

Websocket - The Hoa\Websocket library.

•    PHP

---

Hoa is a modular, extensible and structured set of PHP libraries. Moreover, Hoa aims at being a bridge between industrial and research worlds. This library allows to manipulate the WebSocket protocol and proposes a server and a client. It supports two specifications RFC6455 and Hybi (at the same time).

sSocks (Socks5 Server)

•    C

---

sSocks is a package which contains: a socks5 server implements RFC 1928 (SOCKS V5) and RFC 1929 (Authentication for SOCKS V5), a reverse socks server and client, a netcat like tool and a socks5 relay.

PHP-Websockets - A Websockets server written in PHP.

•    PHP

---

This project provides the functionality of an RFC-6455 (or Version 13) WebSockets server. It can be used as a stand-alone server, or as the back-end of a normal HTTP server that is WebSockets aware. In order to use PHP WebSockets, you must have the ability to arbitrarilly execute scripts, which almost always means having shell access to your server, at a minimum. It is strongly encouraged that you have the ability to configure your machine's HTTP server. It is strongly discouraged to allow arbitrary execution of scripts from a web interface, as this is a major security hole.

ice4j - A Java implementation of the ICE protocol

•    Java

---

The Interactive Connectivity Establishment (ICE) protocol combines various NAT traversal utilities such as the STUN and TURN protocols in order to offer a powerful mechanism that allows Offer/Answer based protocols such as SIP and XMPP to traverse NATs. This project provides a Java implementation of the ICE protocol that would be usable by both SIP and XMPP applications. The project also provides features such as socket sharing and support for Pseudo TCP.

WebSocket-Node - A WebSocket Implementation for Node.JS (Draft -08 through the final RFC 6455)

•    Javascript

---

This is a (mostly) pure JavaScript implementation of the WebSocket protocol versions 8 and 13 for Node. There are some example client and server applications that implement various interoperability testing protocols in the "test/scripts" folder. For a WebSocket client written in ActionScript 3, see my AS3WebScocket project.
